How we approach dome rooflights in Cowes
Thinking about dome rooflights in Cowes? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Cowes, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Neighbouring towns include Newport, Isle of Wight (7 km) and Ryde (10 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Cowes
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
Our planning guide covers each nation in more detail.

Common questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
How do I book a survey in Cowes?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Cowes?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
